EZ FLO BALL VALVE COUPLING CONNECTORS:

Ball Valve Coupling Connectors are available in sizes ranging from 3/4" to 4" with socket x socket connections for gluing into PVC pipe. They are manufactured from Schedule 40 PVC with 1/4" nylon barbed tubing connections. They are used to connect the EZ-FLO system to the irrigation flow line before or after the valve with the 1/4" flexible tubing provided with every EZ-FLO system. They are required for complex system designs or when the elevation of zone valves downstream from the EZ-FLO installation point are at an elevation of 10 feet (3 meters) or more above the installation point or where the user needs more control over the operation of the fertigation unit. Ball Valve Connectors provide the ability to adjust the differential pressure between the inlet and outlet connections to the irrigation flow line and can ensure that even the heaviest organic fertilizers and supplements can be pulled from the tank.

Ball Valve Coupling connectors are highly recommended for use with EZ005-FX and EZ010-FX models and REQUIRED FOR all High Capacity (HC) main line units.

Ball Valve Connectors provide the ability to adjust the differential pressure between the inlet and outlet connection to the irrigation flow line. They are also recommended for any application where higher feed rates are desired or heavier fertilizer/supplement products are used. This is especially important to nurseries and growers where higher proportioning rates are needed.

EZ-FLO Systems are Easy to Install and Easy to Use

EZ-FLO Systems can be installed in minutes. We recommend that they be installed in an underground valve box but they can also be hidden under decorative rocks or housed in above ground structures when necessary. The only requirement is that they be installed after an approved backflow prevention device as determined by local plumbing code.

EZ-FLO main line systems are installed after the backflow prevention device and normally before the irrigation zone valves to allow the unit to feed all irrigation zones. A typical installation is shown here:

In this configuration, when an irrigation zone valve is turned on, the EZ-FLO fertigation unit automatically adjusts to pressure and flow and precisely meters out the appropriate fertilizer based on the water volume flowing into that zone.

Typical Installation

The system is normally installed in a valve box, connected to the main line of the irrigation
system after the back flow preventer and before the sprinkler valves. One unit will feed both
drip and sprinkler zones that are downstream from the connection point.
